[Swansea Hackspace] An old PC with parallel printer port?

[Justin Mitchell]

If you have a have any kind of wiring / pinout for the current parallel
connector that would be a great help.

but it sounds like a perfectly reasonable goal to just wire that
connector to an arduino board running the firmware i previously
mentioned, which will make running it much easier.
